One of these trends in 1953 was the initiative by the prime-minister of the Conservative Cabinet of Winston Churchill to the form a new security system in line with the international detente. The article analyzes a little-known in the Russian historiography initiatives offered by Winston Churchill to establish a dialogue with the Soviet Union and to organize a summit to discuss and resolve the German question and other security problems. The author of the article builds the material in the logic of the “three circles” concept, referring to the assessment of the Anglo-American relations and the policy of Great Britain in the field of European integration. Particular attention is paid to the issue of a European army and holding of the Berlin Conference and the Geneva Conference in 1954.
